Series: EC | Carrier: Approx. 40,000–66,000 lbs (20–33 t)
The Epiroc EC 135 is a hydraulic breaker built for contractors, rental fleets, demolition crews, quarry operators, and equipment owners who need a breaker that fits their carrier correctly and delivers reliable output in the field. This model sits in the Epiroc EC range and is well suited for site preparation, road base breaking, foundation work, utility trenching in mixed material, and general concrete demolition. When a breaker is matched correctly to the carrier — by weight class, hydraulic flow, and operating pressure — operators get better production, less unnecessary vibration transmitted back to the machine, reduced wear on the attachment and bracket, and fewer problems with hoses, bushings, retainers, and seals.
The Epiroc EC 135 is positioned between the EC 122 T and EC 135 T in the Epiroc EC series, designed for approximately 40,000–66,000 lbs (20–33 t) carrier weight, with a service weight of approximately 2,900 lb (1,315 kg). The tool steel diameter is approximately 130 mm (5.1 in), oil flow requirements are approximately 34–42 L/min (9–11 gpm), operating pressure is approximately 2,200–2,500 PSI, and the impact rate is approximately 490–650 BPM. These specifications define where this breaker fits in the lineup. A unit that is too small for the job will force the operator to work the tool harder than intended, causing overheating and premature wear. A unit that is too large for the carrier can create excess hydraulic heat, damage mounting hardware, and shorten the service life of both the hammer and the machine.
Maintenance discipline is as important as correct sizing. A hydraulic hammer operates in some of the most demanding conditions on a jobsite — dust, shock load, side load, heat, moisture, and thousands of impact cycles per hour. Even a well-built breaker will lose performance if the lower bushing wears undetected, the tool is run dry, the seals harden from heat cycling, nitrogen or accumulator pressure drifts out of specification, or hydraulic flow and pressure fall outside the recommended range. Owners should inspect the tool steel, retainers, bushings, tie rods, hoses, fittings, and the grease system on a regular schedule. A properly maintained hammer hits harder, runs cooler, and protects the carrier better than a neglected one. For many contractors, the real value of this model is not the purchase price alone — it is the ability to keep it running through repairable wear rather than replacing the whole breaker.
The design characteristics of the Epiroc EC 135 include Epiroc’s EC-series ContiLube II automatic lubrication, PowerAdapt hydraulic protection, StartSelect operating frequency control, and full-housing enclosure for environmental protection. These attributes make it well suited for applications where productivity, controllability, carrier protection, and access to service support all matter. When comparing this model against similar breakers, pay close attention to carrier size match, hydraulic circuit setup, tool steel availability, and the parts support network available in your area. Matching the hammer correctly to the carrier improves efficiency and helps prevent common issues such as weak hitting, slow cycling, tool overheating, premature bushing wear, and cracked mounting hardware.
HBS provides complete support for the Epiroc EC 135, including hydraulic hammer repairs, full rebuilds, routine maintenance, and sales. Parts stocked and available for this model include chisels (approx. 130 mm tool steel), tie rods, upper and lower bushings, retainer pins, accumulator diaphragms or membranes, hydraulic seals and seal kits, front head components, and hoses and fittings. Whether this breaker is leaking oil, hitting weak, cycling slowly, overheating, wearing tools too fast, breaking retainers, or due for a full overhaul, HBS can diagnose the issue and return it to working condition. Contact HBS for service pricing, parts availability, rebuild options, and expert guidance on matching this hammer to the right carrier and application.
Key Features
- Epiroc EC 135 fills the carrier range between the EC 122 T and EC 135 T, providing a carrier-matched option for 20–33 t excavators in commercial construction and demolition where the EC 122 T is underpowered and the EC 135 T exceeds auxiliary circuit flow capacity on smaller machines in this weight band
- Epiroc ContiLube II automatic lubrication system delivers measured grease quantities to the front head bushing and tool steel at programmable intervals without operator input, maintaining continuous lubrication during high-cycle operation and eliminating the dry-running bushing wear that shortens lower bushing service life when manual greasing is delayed or skipped
- Epiroc PowerAdapt system monitors hydraulic pressure at the inlet and automatically adjusts operating parameters to match the carrier’s actual available flow and pressure, protecting the breaker power cell from the reduced-output conditions that cause blank-fire damage when excavator auxiliary pressure drops below specification during extended use
- HBS stocks parts for the Epiroc EC 135 including chisels, tie rods, upper and lower bushings, retainer pins, accumulator components, hydraulic seal kits, front head parts, and hoses — supporting repairs, rebuilds, and preventive maintenance without extended wait times
